"but can't find the authority that would limit the overall number of days for 2021, either for Sick Leave and Family Leave."

 

The 2021 1040 instructions have this in the What's New section:

Credits for sick and family leave for certain self-employed individuals.

The Families First Coronavirus Response Act (FFCRA) helped self-employed individuals affected by coronavirus by providing paid sick leave and paid family leave credits equivalent to those that employers are required to provide their employees for qualified sick leave wages and qualified family leave wages. The COVID-related Tax Relief Act of 2020 extended the period during which individuals can claim these credits. For more information, see the instructions for Form 7202 and Schedule 3, line 13b.
